Numerical Modelling and GNSS Observations of Ionospheric Depletions due to a Small-Lift Launch Vehicle
G. W. Bowden, M. Brown
Space launches produce ionospheric disturbances which can be observed through measurements such as Global Navigation Satellite System signal delays. Here we report observations and…
Orbit-localised thermosphere density prediction using a Kalman filter based calibration of empirical models
George Bowden
Accurate estimation of thermosphere mass density is critical to determining how satellite orbits evolve over time and thus to planning and managing space missions. Empirical thermo…
Numerical simulation of ionospheric depletions resulting from rocket launches using a general circulation model
G. W. Bowden, P. Lorrain, M. Brown
Rocket exhaust plumes have been observed to cause large-scale depletions of ionospheric plasmas ("ionospheric holes"). In the F-region, charge exchange reactions occur between O^+…
Global Alfven Eigenmodes in the H-1 heliac
M. J. Hole, B. D. Blackwell, G. Bowden +5
Recent upgrades in H-1 power supplies have enabled the operation of the H-1 experiment at higher heating powers than previously attainable. A heating power scan in mixed hydrogen/h…
Calculation of continuum damping of Alfvén eigenmodes in 2D and 3D cases
G. W. Bowden, M. J. Hole, A. Könies
In ideal MHD, shear Alfvén eigenmodes may experience dissipationless damping due to resonant interaction with the shear Alfvén continuum. This continuum damping can make a signific…
A singular finite element technique for calculating continuum damping of Alfvén eigenmodes
George W. Bowden, Matthew J. Hole
Damping due to continuum resonances can be calculated using dissipation-less ideal magnetohydrodynamics (MHD) provided that the poles due to these resonances are properly treated.…
Comparison of methods for numerical calculation of continuum damping
George Bowden, Axel Könies, Matthew Hole +2
Continuum resonance damping is an important factor in determining the stability of certain global modes in fusion plasmas. A number of analytic and numerical approaches have been d…
